Hi Damjan,
I want separate email-thread for the OCTEONTx mempool ops.
> Regarding the octeon tx mempool, no idea what it is,
OCTEONTx mempool ops uses hardware mempool allocator instead of DPDK
software mempool. This is not enabled by default in DPDK but once
enabled all buffers are managed by OCTEONTx hardware allocator.

This I understood that VPP calls rte_mempool_populate_iova_tab() but I
want to know why VPP allocates buffer on its own and not allow DPDK to
create its own buffers? Why VPP cannot call rte_pktmbuf_pool_create()?
Is there a limitation?
Thanks,
Nitin
